Design

The automatic transmission electric controller unit consists of a plastic supporting body on which the following electronic components are located:
- Speed sensors
- Control solenoid valves
- Gearshift solenoid valve
- Starter lockout contact
- Transmission oil temperature sensor

Conductor tracks which are laid in the supporting body make the connection between the electrical components and a 13-pin plug-in connector (13).

The 13-pin plug-in connector (13) forms the connection to the vehicle's cable set and to the electronic transmission-control control unit (N1513).

Except for the solenoid valves all electronic components are permanently connected to the conductor tracks.

Function
Signals from the electronic transmission-control control unit are converted into hydraulic functions in the automatic transmission electric controller unit. The rpm sensors, the starter lockout contact and transmission oil temperature sensor supply input signals to the electronic transmission-control control unit.

The solenoid valves are actuated by the electronic transmission-control control unit and trigger the hydraulic functions.
